Detailed description of the invention
Fig. 1 is the schematic diagram of display floater of the present invention, and Fig. 2 is the schematic diagram of first substrate of the present invention, and Fig. 3 is this
The schematic diagram of invention second substrate, Fig. 4 is the schematic diagram at another visual angle of display floater of the present invention, joins the most in the lump
According to Fig. 1 to Fig. 4.Display floater 100 includes first substrate 110, second substrate 120.Have on first substrate 110
There is visible area 112 and be provided with testing cushion 113 and a plurality of virtual pixel cell 111, second substrate 120 has
There is the first black matrix" 121.
As in figure 2 it is shown, a plurality of virtual pixel cell 111 are surrounded on visible area 112 periphery, such as, a plurality of
Virtual pixel cell 111 can be surrounded on visible area 112 periphery in the square shape closed, and certainly, implements at other
In mode, a plurality of virtual pixel cell 111 also can not close arrangement.A plurality of virtual pixel cell 111 can
The signal of lighting provided by testing cushion 113 is lighted, such as, in the present embodiment, and testing cushion 113
Number be two, i.e. testing cushion 113 can be divided into the first testing cushion and the second testing cushion (distinguishing in Fig. 2),
First testing cushion is in order to provide signal to a plurality of virtual pixel cell 111, and the second testing cushion is in order to provide
Source signal gives a plurality of virtual pixel cell 111, and signal and source signal act on lighting plural number jointly
Individual virtual pixel cell 111, certainly, in other embodiments, the number of testing cushion 113 is not restricted,
Only need to meet and can light a plurality of virtual pixel cell 111.
When to group first substrate 110 and second substrate 120, make the first black matrix" 121 and a plurality of virtual representation
Element unit 111 relatively, and lights signal to a plurality of virtual pixels 111 to light plural number from testing cushion 113 offer
Individual virtual pixel cell 111, if light leak does not occurs in display floater 100, then display floater 100 is correct to group；If
There is light leak in display floater 100, then display floater 100 is to group skew.
Fig. 5 is the display floater of the present invention schematic diagram to group skew, and Fig. 6 is that display floater of the present invention is to group skew
The schematic diagram at another visual angle, refer to Fig. 5 and Fig. 6.When first substrate 110 and second substrate 120 are inclined to group
During shifting, the light that a plurality of virtual pixel cell 111 send has part from the dashed region shown in Fig. 5, Fig. 6
Spill, i.e. there will be light leakage phenomena, say, that if light leak occurs in display floater 100, then can determine whether display
Panel 100 is to group skew.
Further, the light leak degree also by zones of different judges that display floater 100 is to group precision.Figure
7 is the schematic diagram of the present invention the first black matrix", refer to Fig. 7.First black matrix" 121 is at first substrate 110
The width of zones of different different, can be such as the zigzag illustrated, because the first black matrix" 121 is first
The width of the zones of different of substrate 110 is different, when there is light leak in display floater 100, and the light leak of zones of different
Degree would also vary from, and so, can judge the smart to group of display floater 100 according to different light leak degree
Degree.Such as, if light leak does not occurs in first area, and there is light leak in the second area being close to, then can determine whether
Corresponding to first area to group precision be display floater 100 to group precision.
Also being pasted with chip (not shown) on display floater 100, in the present embodiment, chip is aobvious
Show that panel 100 just can be attached after organizing correctly, occur after so can preventing from attaching needing again heavy industry to after group skew
Trouble.Chip provides normally-black signal to a plurality of virtual pixel cell after display floater 100 is correct to group
111, it is provided that when the purpose of normally-black signal is to ensure normally to use display floater 100, a plurality of virtual representation
Visible area 112 will not have been disturbed by element unit 111.
The present invention also provides for the method for testing of above-mentioned display floater 100, in order to detect display floater 100 to group
Situation, method of testing includes:
Step one: first substrate 110 is provided, first substrate 110 has visible area 112, and this first substrate
On be provided with a plurality of virtual pixel cell 111, a plurality of virtual pixel cell 111 are surrounded on visible area 112 weeks
Limit；
Step 2: second substrate 120 is provided, second substrate 120 has the first black matrix" 121；
Step 3: to group first substrate 110 and second substrate 120, makes the first black matrix" 121 and a plurality of void
Intend pixel cell 111 relative；
Step 4: provide and light signal to a plurality of virtual pixels 111 to light a plurality of virtual pixel cell
111, if light leak does not occurs in display floater 100, then judge that display floater 100 is correct to group；If display floater 100
Light leak occurs, then judges that display floater 100 is to group skew.
In above-mentioned step 4, if judging, display floater 100 is correct to group, then enter step 5；
Step 5: attach chip, chip provides normally-black signal to a plurality of virtual pixel cell 111.
First black matrix" 121 can be different, in above-mentioned step at the width of the zones of different of first substrate 110
In four, if judging, display floater 100 to group skew, then enters step 6；
Step 6: according to the light leak situation of zones of different judge display floater 100 to group precision.
Being additionally provided with testing cushion 113 on first substrate 110, testing cushion 113 is in order to provide in above-mentioned step 4
Light signal to a plurality of virtual pixel cell 111.
In sum, the display floater of the present invention is provided with virtual pixel cell at visible area periphery, in display
When panel is to group, is only lighted virtual pixel cell by testing cushion, and visible area is the most luminous, so, can root
Judge that display floater is the most correct to group according to the light leak situation of display floater.Further, also can be according to not
With the light leak situation in region judge display floater to group precision.
Certainly, the present invention also can have other various embodiments, without departing substantially from present invention spirit and the feelings of essence thereof
Under condition, those of ordinary skill in the art can make various corresponding change and deformation according to the present invention, but this
A little corresponding changes and deformation all should belong to the protection domain of appended claims of the invention.
